mill bond work

The ability to simulate theBond workindex test also allows examination of truncated ballmillfeed size distributions on theworkindex. For grinding circuits where the feed to a ballmillis sent directly to the classifier and the cyclone underflow feeds the ballmill(see Figure 3.10), a question arises as to whether this practice will alter the ballmill workindex (BW i) of the material ...
